The BCSR1_* in the  CONFIG_FADS areas are register addresses specific to
the FADS board.
It seems some FADS stuff still hasn't made it into _devel.  Here are the
defines I have:
/* Bits of interest in the BCSRs.
 */
#define BCSR1_ETHEN             ((uint)0x20000000)
#define BCSR1_RS232EN_1         ((uint)0x01000000)
#define BCSR1_PCCEN             ((uint)0x00800000)
#define BCSR1_PCCVCC0           ((uint)0x00400000)
#define BCSR1_PCCVPP_MASK       ((uint)0x00300000)
#define BCSR1_PCCVPP0           ((uint)0x00200000)
#define BCSR1_PCCVPP1           ((uint)0x00100000)
#define BCSR1_RS232EN_2         ((uint)0x00040000)
#define BCSR1_PCCVCC1           ((uint)0x00010000)
#define BCSR1_PCCVCC_MASK       (BCSR1_PCCVCC0 | BCSR1_PCCVCC1)
#define BCSR4_ETHLOOP           ((uint)0x80000000)      /* EEST Loopback */
#define BCSR4_EEFDX             ((uint)0x40000000)      /* EEST FDX
enable */
#define BCSR4_FETH_EN           ((uint)0x08000000)      /* PHY enable */
#define BCSR4_FETHCFG0          ((uint)0x04000000)      /* PHY autoneg
mode */
#define BCSR4_FETHCFG1          ((uint)0x00400000)      /* PHY autoneg
mode */
#define BCSR4_FETHFDE           ((uint)0x02000000)      /* PHY FDX
advertise */
#define BCSR4_FETHRST           ((uint)0x00200000)      /* PHY Reset */
